Objective: To investigate the effects of different operation methods on ovarian function in abnormal uterine bleeding. Methods: 114 cases of abnormal uterine bleeding patients were selected from December 2013 to January 2016 in our hospital for treatment, all patients were divided into three groups according to the random number table, 38 cases of patients in group A received endometrial electrical resection; 38 cases of patients in group B received transcervical resection of endometrium (TCRE); 38 cases of patients in group C received endometrial ablation (EA), the hormone levels of three groups were observed and compared before, 3 and 6 months after operation. Results: Through the comparison, before operation, after operation 3 and 6 months, FSH, LH, E2 levels in group A were rather different, which FSH and LH was rising trend, E2 showed a downward trend, and the result was statistically significant (P<0.05). Although the gonadal hormone concentrations of group B and group C patients fluctuate little, but between or within groups had no significant difference (P>0.05); compared with B, group C, each index in group A were significantly different after 3 and 6 months (P<0.05); the difference of ovulation function recovery in three groups was big, the total recovery rate of the group C (80.95%) and group B (71.05%) was significantly higher than that in group A (40.63%), group C patients recovered the most significantly. The results had statistical difference, P<0.05. Conclusion: Among three surgical methods in the treatment, there are signs of premature ovarian failure after 6 months in total hysterectomy, while endometrial electric cut operation and endometrial operation has little influence on the function of ovary removal,, as endometrial removal operation is simple, and postoperative ovarian function of patients recover better, it is recommended to choose endometrial ablation.
